bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

65b65ffcf6 drm/xe/gsc: Make GSC FW load optional for newer platforms
On newer platforms GSC FW is only required for content protection
features, so the core driver features work perfectly fine without it
(and we did in fact not enable it to start with on PTL). Therefore, we
can selectively enable the GSC only if the FW is found on disk, without
failing if it is not found.

Note that this means that the FW can now be enabled (i.e., we're looking
for it) but not available (i.e., we haven't found it), so checks on FW
support should use the latter state to decide whether to go on or not.

As part of the rework, the message for FW not found has been cleaned up
to be more readable.

While at it, drop the comment about xe_uc_fw_init() since the code has
been reworked and the statement no longer applies.

004311aa7d drm/xe: Convert xe_fb_pin to use a callback for insertion into GGTT
The rotation details belong in xe_fb_pin.c, while the operations involving
GGTT belong to xe_ggtt.c. As directly locking xe_ggtt etc results in
exposing all of xe_ggtt details anyway, create a special function that
allocates a ggtt_node, and allow display to populate it using a callback
as a compromise.

Now that struct intel_dsb_buffer is opaque, it can be made unique to
both drivers, and we can drop the unnecessary struct i915_vma part. Only
the struct xe_bo part is needed.

Duplicate gen2_irq_reset(), gen2_assert_iir_is_zero(), gen2_irq_init(),
gen2_error_reset(), and gen2_error_init() in intel_display_irq.c.

This allows us to drop the duplicates from xe, and prepares for future
cleanups. Although duplication is undesirable in general, in this case
the local duplicates lead to a cleaner end result.

There's a slight wrinkle in gen2_assert_iir_is_zero(). We need to use
non-device based logging until we pass in struct intel_display in a
separate change.

v2:
- Keep xe compat stuff due to series reorder and rebase
- Keep the WARN as regular WARN

965930962a drm/i915/frontbuffer: Fix intel_frontbuffer lifetime handling
The current attempted split between xe/i915 vs. display
for intel_frontbuffer is a mess:
- the i915 rcu leaks through the interface to the display side
- the obj->frontbuffer write-side is now protected by a display
  specific spinlock even though the actual obj->framebuffer
  pointer lives in a i915 specific structure
- the kref is getting poked directly from both sides
- i915_active is still on the display side

Clean up the mess by moving everything about the frontbuffer
lifetime management to the i915/xe side:
- the rcu usage is now completely contained in i915
- frontbuffer_lock is moved into i915
- kref is on the i915/xe side (xe needs the refcount as well
  due to intel_frontbuffer_queue_flush()->intel_frontbuffer_ref())
- the bo (and its refcounting) is no longer on the display side
- i915_active is contained in i915

I was pondering whether we could do this in some kind of smaller
steps, and perhaps we could, but it would probably have to start
with a bunch of reverts (which for sure won't go cleanly anymore).
So not convinced it's worth the hassle.

b3c8fa0d9c drm/{i915, xe}/display: pass parent interface to display probe
Let's gradually start calling i915 and xe parent, or core, drivers from
display via function pointers passed at display probe.

Going forward, the struct intel_display_parent_interface is expected to
include const pointers to sub-structs by functionality, for example:

struct intel_display_rpm {
	struct ref_tracker *(*get)(struct drm_device *drm);
	/* ... */
};

struct intel_display_parent_interface {
	/* ... */
	const struct intel_display_rpm *rpm;
};

This is a baby step towards not building display as part of both i915
and xe drivers, but rather making it an independent driver interfacing
with the two.

v3: useless include additions dropped
v2: unrelated include removal dropped
